Anyone have instructions how to do this? As I recall this car has coils over each plug, and I'm not sure how to remove and replace the coils...don't want to break anything. Thanks in advance for your help.
should be similar to non amg:
Thanks for responding. I had done a search and did read the DIY section thread that jbanks mentioned, and knew my car is significantly different.Use the open wrench 17 or 18 (not sure but one of those size) rest it agaisnt the valve cover and pry it out. I've done it on the Clk430 and CL 55. Try doing the 2 back plugs first. It the hardest one. If you can remove those then don't even try doing just a half job.
These plugs last forever and are expensive so I keep putting mine back in. Are you sure you need the change. Anyway, do not use anti-seize as mentioned however you can use a little dielectric grease around the insulator so the plugs will be easy to remove in 2020.Thanks for responding.

Does my car also have the screws holding the coil packs on, or am I merely going to pry the coil packs off the plugs?
How difficult can I expect the plugs to be to remove without damaging the heads? My car has the original plugs, 7 1/2 years old with 59k miles.
Also, someone advised NOT to use anti-seeze on the new plugs because it might cause me to over-torque them (I will be using a torque wrench, assuming there's enough room to do so).
Appreciate the help.
